Circaea alpina CalPhotos Circaea alpina Enchanter39s Nightshade

The leaves are opposite, ovate, 2–6 cm and coarsely dentate. The 1.5–4 cm (0.6–1.6 in) petioles have a wing beneath. The flowers and fruits are clustered near the top of the fruiting raceme; each raceme bears 15 or less white or pink flowers in mid-May through early September. Each flower has two white to light pink petals 1–1.5 mm (0.04–0.06 in) long with two lobes. The two white sepals are 1–2 mm (0.04–0.08 in) long. The fruit is a small bur with one seed. C. alpina can reproduce vegetatively and via stolons.
